This invention relates to devices for use in musketry and like trainingof the kind comprising a dummy gun or the like having trigger-controlledfiring mechanism for projecting a targetrecording device.

One object of the invention is to provide a device of the kind describedsuitable for use in training with semi-automatic Weapons, i. e. weaponsin which the trigger can be operated a number of times after eachcooking operation.

A further object of the invention is to provide a novel form of cockingmechanism, and triggercontrolled firing mechanism, suitable forincorporation in a device of the kind described.

A further object of the invention is to provide means for readilymounting the gun in operative relationship. with a target carrying framein such a Way that whilst the gun is movable universally relatively tosaid frame, said gun and said frame can also be moved together.

Referring to the drawings:

The stock and butt of the gun are made of Wood, the stock comprisingupper and lower parts I, 2, screwed together and housing the mechanism,front and rear sights 3, 4, being provided, and the Whole devicesimulating a standard riile as regards weight, distribution of weight,and the like. The front and rear sights are designed to give a viewsimilar to that obtained with an orthodox service rifle, and are madeadjustable as and for the purpose hereafter described. The main spring 5(Figure 2) is carried on a rod 6 carried between xed side plates l, 8(Figures 3 and 7), in xed abutments 9, I0, extending across the stop.The main spring bears at that end adjacent the butt of the gun againstthe lixed abutment 9, and, at the other end, it presses against amovable abutment |01 slidably mounted on the rod B. This movableabutment |01 is connected by a sliding plate or bar II (Figure 3)extending along the inner side of the stock to the bolt arm I2 whichcomprises a side extension of the sliding plate II projecting through aslot I3 in the side of the stock. This bolt arm I2 has an extension I4at right angles to the arm, which constitutes an operating piece for`the bolt arm. A short damping spring I5 (Figure 2) is carried on therod between the movable abutment |01 and a shoulder formed on the'end ofthe rod.

A second spring I 6, which may be referred to as the plate returnspring, is mounted on arod II disposed vertically below the rod 6. Oneend of the rod I'I is carried in the iixed abutment 9, and the other endpasses through an aperture in A. slot (Figures 9 and 13) extendingvertically through the stock between the fixed abutment 9 and the buttis provided, through which a clip or block I9 of dummy cartridges(Figure 12) can be passed, the clip falling freely through the stock tothe ground or on to a table or like sur'- iace. Extending longitudinallyacross this vertical slot 2| is a spring strip 22 (Figures9 .and 10)fixed at one end to the xed abutment-9 and towards the other end to thefree side of a V-shaped plate 23, the other side of which is securedtothe stock 2. The free endof the strip 22 projects beyond the edge of theV-plate and is turnedoutwardly at right angles. thereto as shown at 24(Figure 10) in order tobeableto engage .a recess .25 provided intheinnersurface of the stock. .This outwardly turned portion. 24 alsoextends upwardly to .constitute a stop. 2S (Figure 9) .adapted toengagea recess 21 in the lower edge of the sliding plate. lwhen thelatter is .pulledback to..cock .the gun. vThe sliding plate has a camsurface on its sidearranged to Icooperate with the stop. 26- during. thebackward movementofthe sliding plate Ato force the stop intothe recessbin thestock to. free .the path for. the vsliding plate.

Y recess 25 in the stock, thereby releasing thesliding plate Iwhich, under theaction of the plate return spring |6,v is returned intoits-forward position, leaving thev guncocked.

.The energyv .of the main springl 5 is releasedin stages by a sear box--arrangement comprising two sears 39, 3| (Figures 19 and 19A)co-operating .with a rack bar `32 (Fig-ures2,3,.l3)disposed in .thestock between the main A.spring --5 and the sears, the..forward end oftherack bar 32.

being turned down toengage theA rod between4 the spring.. 5 andthe.movable abutment {lb-so that it. is movable. along.- theA inside of thestock by this abutment...Thevertical edges-of the serrationscf the rackbar act asv-stopsand--are suecessively engaged by the searswhicharereleased therefrom'each time the triggerzi` is. operated.

In the .present case the total energy of the spring,

n which cocked, is released in eightstages.

The two searsarerockably mountedY one be hind the otheron pivot pins34,35, mounted in adapted to be inserted into apin bearing loin the sear box. Fach:scar` has tworollersffl,` 4BR,

or 4|, 4|, carried respectively on opposite ends of pins 42, 43, thelatter being rotatably mounted in slot bearings in the side plates 36,the rollers being loosely disposed in recesses in the stock (see Figure4). These rollers 40, 4|, cooperate with sear control bars 45, 46,(Figures 4, 13) slidingly mounted in line with the4 rollers in each sideof the stockl between recessedwalls in the stock and the side plates 36of the sear box. The upper edges of these control bars 45, 4E, areformed at the ends nearer the butt as racks with eight teeth 41, and, intheir central portion, they have a scolloped or wave formation having vespeaks' 48, the distance between each adjacent Vpair ofpeaks being equalto the distance between two serrations of the rack bar 32. The

' waveedges of the bars support the sear rollers. `The twosear controlbars are in line with the two operating lugs 2D on the movable abutmentIll, and are moved by them into the cocked posi- `tion shown in Figures13 and 16. In the. cocked tance between adjacent .peaks 48 on thebars.and

to one-third the distancebetween centresotthe two pairs of rollers a9,4|,carried respectivelyon the sears.

The arrangement vissuch that when the.. gun hasbeen cocked, and afterloading, (Figure 16),

vthe control bars 45, 46, are in suchagposition relatively to the twosearsthat peaks 48.0n. the two bars acting on .the rollersof thefrontsear 3| lift the latter out'of engagement withthe rack bar 32,whilst the back Sear 3|), the rollers of which are in a depressionhalf-.way between .two peaks 48 of thecontrol bars, is lower than theliront sear and Uengages the rack bar. When the trigger is pulled thecontrol bars 45,46. are displaced forwardly, with the result .that peakson the bars lift the rollers of the back sear, which isV thus lifted outof engagement with the rack bar, Whilst simultaneously the. peakspreviously supporting the rollers of the front sear are moved forwardlyin order to allow the frontsear to drop. AThe rack bar 32, released by;the back sear, moves quickly forward, ,under the. action of the mainspring, for a distance equal to that betweenV two teeth of the racks onthe control bars 45, 4B,.i..e. equal to half the distance betweentheserrations of the rack bar 32, or half ,thedistance between two peaks43 on the control bars 45,45, .when

, it is stopped abruptly-"bythe front sear, as shown vvin Figure 17.

The.- momentum of the suddenly arrested rack is imparted to a.targetirecording v device in the manner. hereafter described. .The

operation is repeated when the trigger .is .again pulled, the sears,after; the second .trigger operation, resuming the position of .Figure15, the parts being then as shown Vin Figure 18. The sears thus.` actalternately to .arrest the4 forward movement of the rack bar untiltheJlatter reaches the end of its movement vafter eight operations ofthe trigger.

A pivoted latch 5|' is actuated by the slideLbar l, when the mechanismis being cocked, to. lift the frame out of engagement withthe racks onthe control bars, to permit the latter 4to be 75.

moved into the cocked,positionthe action `of -p1ate'161.

Hthe bearings. VE() the plates 58, 581 are moved from the position thelatch 5|,being illustrated in Figure 15. After cocking, when the partsare in the relative positions shown' in Figure 15, the dummy clip ofcartridges 22 is passed through the slot 2| as above described torelease the stop 26 and permit the bar to return from the position shownin two side plates 58, 581 (Figures 2, 5 and 8), piv- -otally mounted onalpin 59 fixed transversely of the stock.` A spring 60 mounted on therod 56 bears at one end against the pin bearing 51 (Figure 5) and at theother end against a shoulder 511 (Figure 13) formed on the rod 56. Asecond pin bearing 6| is disposed between the plates 58, 581 and hasslidingly mounted thereon a rod 62,

one end of which passes through a bracket 63 and is secured to a pin 64.A spring 65 is mounted on the rod 62 and has one end bearing against thebearing 6|whilst the other end bears against a flange 66 on the rod 62.The pin 55 is guided between two inwardly curved leaf springs 61, 811,one end of each of which is Asecured to the stock (Figure 8A).

- The means for projecting the dart 55 to pierce a target comprise anintermediate member 68 (Figures 2 and l1) normally disposed and movablyarranged between the plate 16 and a lower As shown inFigure 11, themember 68 comprises a plate having one end turned upwards toconstitute-an abutment surface for the end of the rod 56, and having itsother end formed with three downwardly directed tongues,

Aviz: two outer tongues and a central tongue "disposed between andshorter than the two outer tongues.

arrangement of tongues (Figures 2 and 13), 'which in' this case areupwardly turned, the purpose of which will also be described later. -Inthe arrangement described, whenever the `rack bar 32'moves'forward underthe action of vits spring it projects the member 68, and with it therodI 56, the'latter sliding easily through its bearings and compressingthe spring 68 against Under the pressure of the spring shown in fulllines in Figure 5 to that shown in dot and dash lines, in which latterposition they bear against a stop 10, this movement of the V'platescompressing the spring 65. The forward swinging lmovement of the plates58, 581 has for Veffect to raise the pin 55 Whilst it is being pro-`jected from the gun from the position shown in lfull lines (Figure 5) tothe position shown in dot and dash lines, in which latter position itis"inthe-line of sight represented by the dot and Immediately afterprojection of J:.581to thefull-line position.. The member-68 -isalsoreturned to the starting. position shown `in Figure 2 by the rod 56;during this return movei ment the tongues on the member 68 are raisedclear of the rack by the tongues on the plate 161. Since the rack bar 32is only permitted by the Sear box to move forwardly at any one time adistance equal to one-half the spacing between the teeth, the distancebetween the ends of the outer tongues on the one hand, and the end ofthe central tongue on the other hand, of the member 68, corresponds tohalf the length of the spacing between the teeth of the rack bar, topermit these tongues alternately to engage the rack teeth.

Figures 20-25 illustrate how the gun described may be operativelyassociated with a target. In these figures the target is printed on apaper sheet 8U which is carried on a rectangular frame, the uprights 8|of which are extended above and below the horizontal members 82 and areslidably arranged in guides 83, 83 and 84,84, secured to members 85suspended from hooks 86. These hooks 86 are screwed into the tophorizontal member of a frame 81, which is hingeably connected to atriangular base 88 on which it is supported by a strut 89, the upper endof which is hingeably connected to the top horizontal member of theframe 81, and the lower end of which is connected to an angle bracketwhich is suitably slotted to engage a screw carried in the base 88, thescrew being engaged by a wing nut 90.

The target frame is held in position at the required height by turningscrews 9| engaging in the guides 83, whereby the inner ends of thescrews press the uprights 8| against the members 85.

The gun is operatively associated with the target by means of a yokecomprising a rod or bar 92 bent over to form a closed link but leaving aprojecting end 921 adapted to be engaged by the turned over end of aconnecting member 93, the other end of which is formed with a hook 94adapted to be engaged, .and universally movable in, an aperture 95formed in a bracket 96 having a recess 91 by means off which it canengage a screwed member 98 projecting from a cross bar 99 carried on theback of the suspended uprights 85.y The turned over end of the mem- ,berV93 is secured by a wing nut 931 engaging a screw on the member 93 andthe bracket 96 is secured to the bar 99 by a wing nut 981 engagingthescrew 98. `Rotary movement of the member 93 on the end 921of the bar92 is prevented by means of a stop 922 projecting from the upper edge ofthe end 921. The front end of the link hasvtwoY discs or flanges 932constituting stops for the purpose hereafter described. The link issuitably curved as shown in Figures 20, 21, to permit the hand to bemoved thereunder if and when the gun is resting on a support duringaiming and firing. With the arrangement described it will be evidentthat the link and the guncarried thereon can be moved universally aboutthe aperture 95.

As shown in Figures 1, 2 and 24, the gun has a vertical recess |88 inthe top of the stock, the

`free edge of which can be lclosed by a catch comprising a plate |04pivoted at |95 and having'an upturned yend |06 constituting a thumbpiece for ready operation. In order to mount the gun in association withthe target (Figure 21) the stock is passed through the closed link 92and that part of the front end of the link between the two discs 932 isengaged in the vertical recess |00, whereupon the catch |04 is movedover to close `EN'Lswinging inwards the uprights 85 andl parts carriedthereby and the strut 89, and folding up the Abase 88.

Means are provided for testing the accuracy of the path of movement ofthe piercing end of the rod relatively to the line o-f sight during procjection of the rod, and for making any necessary adjustment to the lineof sight to accommodate the latter to the path of the rod. These meanscomprise means for vertically adjusting the foresight 3 and forllaterally adjusting the rear sight 4, and means for xing -a plain sheetof paper to the front end of the gun. As shown in Figures 2 and 13 theforesight 3 is carried on a plate H screwed against pressure from aspring Il on to the stock. The sight can be adjusted vertically byvarying the screw setting. The rear sight 4 is, as shown in detail inFigure 27, carried on a screwed rod H2 mounted in bearings H3, H3 on thebase plate H4 screwed tothe stock. By turning the nut H5 secured to thescrew H2 the sight 4 can be moved across" the stock.

Figure 26 illustrates a frame H6I to which is -secured for example bypasting a blank paper sheet H7. The frame has a recess H8 adapted toengage a screw H8' projecting from the front end of the gun (see Figure1), the frame being secured by tightening the screw. In order to testthe accuracy of the path of movement of the pin 55 relatively to theline of sight the frame H6 is fixed to vthe gun in the manner described,and the trigger is pulled to project t-he pin 55 to pierce the papersheet HT. The gun is then sighted to ascertain if the perforation isinaccurate alignment withthe line of sight. If not,

'the sights require adjustment.
